太酷了！{:soso_e100:} 谢谢楼主的分享{:soso_e179:} 麻烦您能不能将《永磁电机计算程序（电压向量图v1.0）.zip》发我一份 364076295@qq.com ，谢谢了 本帖最后由 戒僧和尚佛缘 于 2015-9-23 16:24 编辑
原先下过的同学能帮忙再传上来吗 把源码粘到vb6.0中编译出不出来程序 戒僧和尚佛缘 发表于 2015-9-23 16:23
把源码粘到vb6.0中编译出不出来程序
因为缺少窗体及上面的按钮等可视化对象，vb不像vc，只贴代码编译不了程序。，你照着程序，动手画下窗体、按钮，就能编译了。 部分论坛网友反映无法下载，重新上传下附件， 戒僧和尚佛缘 发表于 2015-9-6 16:30

已发，请查收~~~~~~~~~~~ 谢谢楼主的分享{:soso_e100:} 楼主真是雷锋啊，太好了，看到楼主用vb编写的界面非常不错啊，我想用vc实现异步起动永磁同步电机电机的编程，也是按照唐老师那本书上的，但是到工作特性计算模块出不来了，不知道楼主有没有尝试用vc编写啊？ dzl2014 发表于 2015-10-13 20:54

不客气。书上工作特性计算那篇，稍微复杂点的就是几个循环和查表，用vc肯定能编工作特性计算。我喜欢用vb6，就是因为简单且够用。 dzl2014 发表于 2015-10-13 20:54

我在另一篇帖子上发过一个永磁计算程序（后来学Maxwell，没有细致调试），使用vb编的，有工作特性计算的源码，你用vc可以参考 limengde2001 发表于 2015-10-14 19:22
